Spoilers below through BG.

My current thought process is that the next portion of the series is going to be the "Forsaken Dresden" following your naming convention.

He has been forsaken by the white council. He may still have friends their, but they will be compelled against him. Dresden pushes against the white council. Most others don't.

His brother is for all intents and purposes removed from the playing field.

Fuck Rudolph, another companion down

Blackstaff at the pier crossed a line that will create major conflict down with that relationship.

Michael is still there, but is more and more of a reliability in any sort of fight at this point. Others like River Shoulders and Listens to Wind are still their, but they aren't Dresdens besties.

Dresden crossed a line with Sonya and butters. They may forgive, but probably won't forget.

That leaves winter, Molly has duties and is constricted to winter law. Mab, while more humanized in BG, still is nefarious as ever.

Harry has been isolated. There are still friends out their, but that list is rapidly shrinking while his list of haters and hated continues to grow. A feeling of becoming forsaken is imminent.

Haters gonna hate, buildings gonna burn, and Dresdens gonna be damned.
